Henry the Young King of England (born 1155)

Henry the Young King was the eldest son of Henry II of England and Eleanor of Aquitaine to survive childhood. In 1170, he became titular King of England, Duke of Normandy, Count of Anjou and Maine. Henry the Young King was the only English king since the Norman Conquest to be crowned during his father's reign, but he was frustrated by his father's refusal to grant him meaningful autonomous power. He died aged 28, six years before his father, during the course of a campaign in Limousin against his father and his brother Richard.
